FWIW, in my ideal world, `let` would have the semantics of the current
`let*`, and for those few cases where we do want the "parallel"
semantics, we'd have a special `let-parallel` or something.
But this is not really an option at this point.

For that same reason, while I'd prefer the `when-let` name with the
`when-let*` semantics, I think this won't fly.  Just as happened with
`dlet` it would be changed in due time either by adding a `*` or by
changing the semantics.
